“…Total removal percentage of oil content up to 93% with MF as pre-treatment step and up to 99.5% with UF followed by NF as final treatment was shown. The oil removal efficiency results obtained from experiments show good agreement with those available in the literature [e.g., [17][18][19][20][21]. Mueller et al [17] studied two ceramic membranes (0.2 and 0.8μm pore sizes) for the treatment of oily water Hueneme field in California.…”

Efficient performance of the combination of treatment processes for oilfield produced water generated from oil tank dewatering was investigated in the study presented below. Byproduced wastewater is generated in significant quantity during exploitation of crude oil and gas from onshore and offshore production operations. This wastewater, commonly referred to as "produced water", has distinctive characteristics, due to their organic and inorganic compounds. However, these characteristics change from well to well. The treatment process investigated here consists of a pre-treatment step utilizing microfiltration (0.1 and 0.2µm pore size filters) and/or a simulated batch dissolved air flotation (DAF), and a multistage posttreatment step utilizing cross-flow ultra-(0.05µm pore size and 20kDa molecular weight cutoff filters), and nanofiltration (1 and 0.75kDa MWCO filters). Filters used were ceramic membranes. To determine the separation capability of the processes described, various parameters, such as trans-membrane pressure varying from 0.5 to 2 bar, cross-flow velocity in the range of 0.6 to 1.3m/s, influent oil concentration ranging from 32 to 5420 parts per million (ppm) and different membrane cleaning methods used were investigated. The average permeate flux varied from 3.4 to 3300 l/h*m²*bar, total oil removal was up to 99.5% and total organic carbon removal reached 49%.

“…[94][95][96] Employing ceramic filtration membranes for oily wastewater treatment is also studied and reported by some researchers. [96][97][98][99][100][101][102][103][104][105][106][107][108][109] Because of the limitation of their pore sizes, directly employing ceramic membranes for the separation of emulsified oil/water mixtures would cause severe fouling problem and low fluxes. 99,104,108 Among the various ceramic filtration membranes, zirconia ceramic membranes exhibit better performance than others for oily wastewater treatment.…”

The separation of oily wastewater, especially emulsified oil/water mixtures, is a worldwide challenge because of the large amount of oily wastewater produced in many industrial processes and daily life. For the treatment of oily wastewater, membrane technology is considered the most efficient method because of its high separation efficiency and relatively simple operational process. In this short review, the recent development of advanced filtration membranes for emulsified oil/water mixture separation is presented. We provide an overview on both traditional filtration membranes, including polymer-dominated and ceramic-based filtration membranes, and recently developed nanomaterial-based functional filtration membranes, especially one-dimensional nanomaterials, for effectively treating emulsified oil/water mixtures. The liquid flux and antifouling property, which are the most important factors for membrane performance evaluation, are described for different types of membranes. Conclusions and perspectives concerning the future development of filtration membranes are also provided.

“…However, the permeate flux of traditional membrane separation decreases rapidly with time due to membrane fouling and concentration polarization. Therefore, several physicochemical methods have been developed to mitigate membrane fouling and enhance filtration such as adding reactive salts (Belkacem et al, 1995), coagulation/flocculation pretreatment (Zhong et al, 2003) and dynamic shear enhanced processes, i.e., rotating membranes and vibratory shear enhancing process (VSEP) (Ersahin et al, 2012;Jaffrin, 2008;Zhang et al, 2013). According to the report of Belkacem et al, the membrane flux was greatly enhanced by adding low dosage of inorganic salt.…”
